What is Volcano?

Volcano is one of the natural disasters, it is a mountain that opens downward to a pool of molten rock under the surface of the earth. When the eruptions happen, gases and rock will shoot up though the carter and fill the air with lava fragments. An erupting volcano can cause earthquake, rockfalls, tsunamis,etc. Therefore, it can kill thousand every year.

Volcano 1997

Volcano is a disaster film from 1997 which is directed by Mick Jackson. This movie is produced in United State. It is about when a massive earthquake rocks the city of Los Angeles, Emergency Management department head Mike Roark returns from his vacation to help with the city's response. After geologist warns that a volcano may be forming in sewer tunnels, another severe earthquake unleashes the lava flowing underfoot destroying the city. So, Roark and Barnes need to solve that out.

How does Volcanoes form?

Volcano form when chambers of magma or hot molten rock boil to the surface. Between the eruptions, these magma sealed for hundreds of year between hundred of year until the pressure builds to break through a vent. The blast creates a crater, where lava and ash flow to form the cone.

Location

This movie is located in MacArthur Park, Cedars-Sinai Medical Center and La Brea tar Pits in Los Angeles, California. It is in United Staes of America. In real life, the location of the film didn't have a real volcano.


Volcanoes are found along destructive plate boundaries, contrastive plate boundaries and at hot spots.

Los Angeles is located neither near a hot spot nor a subduction zone. And the map below tell us where volcano should locate.

However, the volcano in the film - Volcano 1997, it is surrounded with buildings and real volcanoes are usually located in destructive plate boundaries, contrastive plate boundaries and hot spots. Therefore, it is impossible to have a volcano in the location from the film.

Types of Volcano and Lava

There are many types of volcano in the real life, like Composite Volcano, Cinder Cone Volcano and Shield Volcano.


Volcano 1997's Volcano is a Shield Volcano. There are two major type of volcano: aa and pahoehoe. Aa flows most obviously by very rough up top surfaces, dense interiors and sometime rough bottom surfaces. Hawaiian volcanoes are absent true block lavas. The dense interior what actually flows when it is emplaced. Also, it carries the clinkers along with it.


From the film, it happened like that, from the clip 2:33-2:48 (Volcano 1997).

Comparisions

If this was rated from 1 - 10 with 10 being very realistic, I would rate it 5. As the volcano in the film and the volcano in real life does not seem alike because the lava from the real life volcano flows differently from the volcano in the film. However, there are also some similarities such as the colour of the lava is similar in both pictures and it's surroundings are a lot darker than the lava.


From Volcano 1997's clip, 1:02 to 1:50, the lava kept falling down from a high distance. In the real life, the lava won't fall that high. They just flow from the volcano. Therefore, the lava in the clip is very different from reality.

Case Study

One of the volcano which happened in the real life is happened in Mount Tambora which is happened on 10 April 1815. Mount Tambora is located in Indonesia. This place produced the largest eruption known in the world during the past 10,000 years from that time.


This volcano erupted more than 50 cubic km of magma and collapsed afterwards to form a 6 km wide and 1250 m deep caldera. This eruption produced global climatic effects and killed more than 100,000 people.

Conclusion

In conclusion, the clips from the film show that the hazard is not very realistic, and through research, it is shown that there are also similarities from the clips and from real life, although most of it is not very realistic, the film could have been done better if the hazard wasn't so exaggerated, although Hollywood exaggerated it so it could show the watchers what the hazard was. Through the case study, I found out that the location in the film is not suitable for a real volcano as there is many buildings around, and volcanoes need space whilst that area is surrounded by many buildings. This hazard is more realistic than [INSERT MOVIE] because it is not as exaggerated as that one.
